Dunmail Raise is the name of a large cairn in the English Lake District, which may have been an old boundary marker. It has given its name to the mountain pass of Dunmail Raise, on which it stands. This mountain pass forms part of the only low-level route through the mountains between the northern and southern sides of the Lake District. According to local tradition, the cairn marked the burial of a king named Dunmail who was slain by Saxons. The place name itself may well be derived from the name of the historical Dyfnwal ab Owain, King of Strathclyde.
